Popis: The taxonomy of the genus Capsicum has distinguished more than twenty species of peppers with only C. annuum L. being a vegetable of economic importance. The remaining species can, however, be used in breeding via interspecies hybridization as a source of valuable functional traits. The aim of the study was to obtain interspecific hybrids of peppers with increased agronomic potential and their molecular identification. Based on their agromorphological characteristics, the obtained hybrids (‘Anchi’ × C. frutescens L.)F1 and (‘Anchi’ × C. baccatum var. pendulum)F1 formed fruits that had the combined functional traits typical of the cultivar ‘Anchi’, with a high content of soluble solids and dry matter characteristic of pollinators. To identify hybrids and their parental forms, the random amplified polymorphic DNA polymerase chain reaction (PCR-RAPD) and inter simple sequence repeat polymerase chain reaction (PCR-ISSR) techniques were used. The polymorphic products obtained in both methods totalled 65% and 59%, respectively, and they allowed for the identification of all tested genotypes, excluded the possibility of self-pollination of ‘Anchi’ plants, and confirmed the hybrid characteristics of the crossbreed (‘Anchi’ × C. frutescens L.)F1.
